I will check today those fuses with a test lamp or with an ohm meter and post results.

For those who asked where the car is: Spain.

Maybe there is an aftermarket electric door lock as you said.. I don’t know yet. There is no remote control.

The door lock (when it worked) locks/unlocks all doors when any of the front door keys where locked/unlocked. Or when inside the vehicle the drivers door was locked, it locked all doors..
